摘要
DU Weisheng, who is in charge of the National Library of China's Ancient Books Restoration Group, is 6S years old, but still vigorous. With 40 years of experience, Du feels a bit like a doctor of ancient works, and his job is to treat their illnesses. Du plays a very important role since he is an inheritor of the national intangible cultural heritage in the restoration of ancient books.
The restoration of old books remains a manual profession that relies on the intelligence and skill of the workers,who must have a good knowledge of not only classical Chinese culture,but also basic sciences such as chemistry and physics.
